SHEET-METAL RADIATOR.

Specification of Letters Patent.

Patented June 5, 1906.

Application filed January 30,1904. Serial No. 191,329.

To aZZ whmn it 'may concern:

Be it known that I, WILLIAM R. KINNEAR, a citizen of the United States,and a resident of the city of New York, State of New York, have inventednew and useful Improvements in Sheet-Metal Radiators, of which thefollowing is a specification.

This invention relates to radiators.

It has for an object to provide means contained within the radiator forthe purpose of cutting off a number of the units therein withoutinterfering with the circulation of the heating medium through theremaining units in order that the heating capacity may be reduced orincreased at will.

Other and further objects will. appear in the following description andwill be more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a sectional detail view through a radiatorhaving embodied therein the improved means for cutting off a pluralityof units or a section of the radiator, while maintaining the circulationof the heating medium through the remaining units. Figs. 2 and 3 aredetail views of parts shown in Fig. 1.

The radiator consists of a series of vertical units having horizontallyalined connecting or circulation passages at its bottom.

For the purpose of cutting off a plurality of units or a section in aradiator, while leaving the remaining units open to the circulation of aheating medium, I employ valves 18, Fig. 1., adapted to seat against thebosses 2, and an ad ustable rod or hollow member 19, on which saidvalves are threaded, as shown at 20. The valves 18, as shown in Fig. 3,are provided with groove-lugs 21, which engage fixed studs 22 in theradiator to prevent said valves from turning. The adjusting-rod 19 maybe turned by handle 22, passing through stuffing-boxes 23 and connectedto the rod 19 by a stem 24:. By turning the handle 22 in the appropriatedirection valves 18 may be forced to or from their seats and out off thecirculation of the heating medium from the units beyond such valves. Therod 19 is hollow, however, and open or otherwise constructed to admitthe circulating medium at one end, while near its other end or beyondthe valve adjacent thereto are provided perforations 25, through whichthe heating medium may flow.

The radiator illustrated in the drawings is a steam-radiator in which nocirculation-passages are provided at top; but my invention is applicableto other types of radiators.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In combination with radiator units having circulating-passagesconnecting them at one of their ends, valves seating against two of saidpassages, an adj usting-rod upon which said valves are threaded, meansfor securing said valves against turning, and means extending to theoutside of the radiator for turning said adjusting-rod.

2. In combination with radiator units hav ing circulating-passagesconnecting them at one of their ends, valves seating against two of saidpassages, an' adjusting-rod upon which said valves are threaded, meansfor securing said valves against turning and means extending to theoutside of the radiator for turning said adjusting-rod, saidadjustingrod having a circulating-passage through it, comniiunicatingwith the units beyond said valves and maintaining circulationindependently of the units that are cut off.

3. In a radiator, the combination with a plurality of units providedwith alined connecting-passages between adjacent units, of a pair ofvalves for cutting out a portion of the radiator, and a hollow memberextending through the alined passages and forming a connection for theportions of the radiator on both sides of the cut-out portion.

4. In a radiator, the combination with a plurality of units providedwith connectingpassages, of a pair of valves for cutting out a portionof the radiator, and an adjusting or controlling rod for the valvesprovided with a passage-way connecting portions on both sides of thecut-out portion.

The foregoing specification signed this 14th day of January, 1904.
